    Abstract: The invention relates to a cosmetic process for caring for or making up keratin materials, comprising either the topical application to the keratin materials of an (extemporaneous) anhydrous mixture of a cosmetic composition comprising a maleic anhydride acrylic polymer and of an amino alkoxysilane compound (I); or the sequential application to the keratin materials of an anhydrous cosmetic composition comprising a maleic anhydride acrylic polymer and of an amino alkoxysilane compound (I), wherein said maleic anhydride acrylic polymer is obtained by polymerization of:(a) 50% to 90% by weight, relative to the total weight of monomers, of isobornyl (meth)acrylate (b) 1% to 50% by weight of maleic anhydride (c) 0% to 49% by weight of additional (meth)acrylate monomer; said amino alkoxysilane having the formula (I): R—NH—R1Si(OR2)z(R3)x  (I) in which: R1 is a C1-C20 hydrocarbon-based divalent group, R=H or a C1-C4 alkyl group, R2 and R3 represent an alkyl group comprising from 1 to 6 carbon atoms; z denotes an integer ranging from 1 to 3, and x denotes an integer ranging from 0 to 2, with z+x=3. Uses: skin-tensioning agent, makeup, hair fixing.

    Abstract: The invention relates to a cosmetic process for caring for the skin, more particularly facial skin, in particular wrinkled skin, comprising: either the topical application to the skin of an extemporaneous mixture of a cosmetic composition comprising a hyaluronic acid polymer grafted with (meth)acrylate groups and an amine compound; or the sequential application to the skin of a cosmetic composition comprising a hyaluronic acid polymer grafted with (meth)acrylate groups and of an amine compound having one or more primary amine and/or secondary amine groups. The invention also relates to the use of said grafted hyaluronic acid polymer and of said amine compound as a skin tensioning agent.The invention also relates to a cosmetic composition obtained by mixing a cosmetic composition comprising said grafted hyaluronic acid polymer and said amine compound.The invention relates to a kit comprising a first cosmetic composition comprising said grafted hyaluronic acid polymer and a second composition comprising said amine compound, the first and second compositions each been packaged in a distinct packaging assembly.
